When to lock up the converter? Well now that Im running a PT4400 and a 4.10 gear from the old setup which consisted of a SS4000 and a 3.42 gear, its time to wire up the tranny to lock up in 3rd. So what I was wanting to know is when do I need to lock it up?
I DO NOT recommend locking up a Yank converter.
Yank uses a light weight piston that isn't built for being locked up under wide open throttle.
Aren't you running a 200R4? If so, the main problem you have is trying to compare what you car is doing to a 4L60E..

Under the sub-title Lock-up Race Converters is listed the Pro Thruster 4400, which is what Im running. Also under the description says, 245mm, Stall speed 4000 and 4400, Posi Lock-Up Clutch w/Kevlar Linings, lightweight billet cover, 2.5 STR. Why wouldnt I be able to lock it up? I know lots of people locking up their converters. Why wouldnt I be able to?

Psst.. big hint for you.. all LS1 4L60 converters are "lock up" converters. They are designed for drivability reasons to lock at part throttle.

In the past I know that locking the converter was done while running the 1/4 so 4.xx geared cars would not run out or RPM.
I do not think it is a good thing to do. It will put way too much stress on the converter lockup clutch.

WILWAXU, I wasnt kidding. I simply dont know, that is why Im asking. You dont have to get an attitude about it. I know the purpose of locking up the converter for drivability issues, but I didnt know that it was bad to lock it up at WOT. I also know that the 4L60E converters are all lock up. Ive just seen so many people say that they lock their converter up at the track for MPH reasons, slippage at the top end, and if they run out of motor/rpms. Sorry I didnt know...

The problem is you ask 5000 questions, then never listen to what someone tells you. Usually asking the same question time and time again.
Then when you do something totally off the wall and it doesn't work, we get 500 more questions as to why it didn't work..
IMO, talk/type less and read/listen more.

aside from whether it hurts the converter locking it up at wot...it IS an advantage if youre car is set up properly to ulitlize it. Some will have more advantage than others...but it most cases it is an advantage.
tell nmra p/s racer Rich Groh that locking the converter is NO advantage. he will laugh at you.
